Anti-G is expected to react with red blood cells of which phenotypes?

The reactivity of Anti-G is primarily associated with the presence of the G antigen, which is found on red blood cells that carry specific combinations of the D antigen and the C/c antigens. The Anti-G antibody reacts with red blood cells that express both D and G antigens due to their genetic linkage. In the case of the listed phenotypes, the phenotype A+B-C+D-E- contains the D antigen (which is linked to G). Therefore, red blood cells with this phenotype will express the G antigen and are expected to react positively to Anti-G. This explains why Anti-G would specifically interact with red blood cells of this particular phenotype. Other phenotypes in the choices do not express the G antigen due to their lack of the D antigen or a combination that does not lead to the expression of G, resulting in no reaction with Anti-G. Thus, the option that includes both the D antigen and conditions that promote the G antigen's presence is the one that corresponds to the expected reaction with Anti-G.
